Each soldier must be in superb physical condition, possess an unblemished military record and be between 5 feet, 10 inches and 6 feet, 4 inches tall, with a proportionate weight and build.

An interview and a two-week trial to determine a volunteer’s capability to train as a tomb guard is required. During the trial phase, would-be sentinels memorize seven pages of Arlington National Cemetery history. This information must be recited verbatim in order to earn a “walk.”

New sentinels learn the history of Arlington National Cemetery and the grave locations of nearly 300 veterans. They learn the guard-change ceremony and the manual of arms that takes place during the inspection portion of the Changing of the Guard. Sentinels learn to keep their uniforms and weapons in immaculate condition.

The sentinels will be tested to earn the privilege of wearing the silver Tomb Guard Identification Badge after several months of serving. First, they are tested on their manual of arms, uniform preparation and their walks. Then, the Badge Test is given. The test is 100 randomly selected questions of the 300 items memorized during training on the history of Arlington National Cemetery and the Tomb of the Unknowns. The would-be badge holder must get more than 95 percent correct to succeed. Only 400 Tomb Guard Badges have been awarded since it was created in February 1958.

The Tomb Guard Identification Badge is a temporary award until the badge-holding sentinel has honorably served at the Tomb of the Unknowns for nine months. At that time, the award can be made a permanent badge, which may then be worn for the rest of a military career.

Duty time when not “walking” is spent in the Tomb Guard Quarters below the Memorial Display Room of the Memorial Amphitheater where they study Cemetery “knowledge,” clean their weapons and help the rest of their relief prepare for the Changing of the Guard. The guards also train on their days off.
